Both are excellent and closely match each other (and high-end 70-200mm f/2.8 lenses).The reason for the higher overall score can be attributed to the camera used for test as we take into account the noise levels and dynamic range of the camera used for the measurements.

Individual lens metrics provide a clearer indication of the lens performance. While the Nikon lens is a superb performer, the Canon is more consistent in sharpness throughout the zoom range, is slightly ‘faster’, and has lower levels of vignetting and chromatic aberration. Indeed at two microns the Canon zoom has virtually negligible Chromatic Aberration and even the Nikon at 11 microns is quite something given the complexity of a zoom like this.

evaluation unserious

how is it that your assessment is equal to that of the EF 200-400 L IS USM?Because what I see in the site: "http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=764&Camera=453&Sample=0&FLI=1&API=0&LensComp=704&CameraComp=614&SampleComp=0&FLIComp=1&APIComp=0" is so different?

Re: evaluation unserious

Hello,

Thanks for your feedback. The comparison you linked was performed with other cameras (Canon EOS 1Ds Mark III and Nikon D3x). Here is the comparison on dxomark.com : http://www.dxomark.com/Lenses/Compare-Camera-Lenses/Compare-lenses/%28lens1%29/1161/%28lens2%29/409/%28brand1%29/Canon/%28camera1%29/436/%28brand2%29/Nikkor/%28camera2%29/485One other important point is the difference between RAW files analysis as we do and RGB final picture. Depending on the raw conversion, results can vary significantly.
